Singer Taylor Swift has denied having a lesbian relationship with her best friend Karlie Kloss, after some intimate photographs surfaced online.

The singer and her model friend were at the centre of a Twitter frenzy after a grainy picture emerged on social media that appeared to show them kissing at a concert Thursday.

The 24-year-old singer's spokesperson was quick to deny the rumour to Gossip Cop saying the speculation is "hilarious", reports dailymail.co.uk.

In a photograph, they can be seen watching The 1975's performance while leaning on the railings of a balcony area of the concert hall.

In another, Kloss has Swift in a full embrace, left arm wrapped around her shoulders and right hand cupping her face as the `Love story` hitmaker leans in for a kiss while holding on tight to her friend's hand.
